AIGA 066/10 1

Introduction

It is important to follow the principle of “use PPE as a last resort, rather than the preferred option to protect against potential hazards.” This document provides guidance on a work process for selecting and using Personal Protective Equipment (PPE) at work. Selection tables are included which are general examples of PPE for protecting personnel against hazards that could cause harm. The information in the selection tables should not be used without giving due consideration to the prevailing work area and environmental conditions by means of specific task based risk assessments. 2

Scope and purpose

The document is intended to provide guidance and examples in selection and use of PPE. It supplements other techniques for assessing and controlling risk. This document is not intended to replace the need for conducting a task specific risk assessment or to provide details on other administrative or management program elements that can be associated with the proper use of certain types of PPE. Regulatory bodies may have jurisdiction and influence PPE selection and use. 3

General Requirements

3.1

Responsibilities

In accordance with applicable laws and regulations, each location manager is responsible for determining the PPE needs of its facilities, personnel, contractors, and visitors. When necessary, the location manager should ask for support from medical or technical experts in order to assess the medical fitness of employees before selecting the appropriate PPE. 3.2

Risk assessments

A risk assessment should be conducted and documented in each work area to assess the risks related to the process, relevant tasks and activities associated with the work area. The risk assessment should be updated when changes are made in a work area that might impact PPE selection. When undertaking the risk assessment the following steps are recommended: a) b) c)

3.3

Involve the user representatives in the risk assessment process. Assess the risks associated with specific work areas and tasks to determine the need for PPE. Select the PPE that matches the relevant risk. Ensure relevant regulations codes, standards, and PPE specifications are reviewed. (1) Maintenance

PPE shall be checked before each use and shall be regularly cleaned, maintained, repaired (unless disposable) and replaced in accordance with the manufacturer’s instructions. Records of maintenance shall be kept where required. 3.4

Storage

Storage methods shall be in accordance with the manufacturer’s instructions. In some cases, specific storage receptacles for PPE not in use may be required to prevent contamination and keep PPE clean. 3.5

Training

Personnel required to use PPE shall be trained in the following areas: –

The hazards which the selected PPE is being used to protect against.

1

AIGA 066/10 – – –

It’s proper selection (what, when and where to use it); It’s use (e.g. how to put on, fit, adjust and remove) and limitations; and Its proper care, useful service life, disposal, and any required maintenance.

Use of PPE by personnel shall be monitored and any misuse corrected and recorded. 3.6

Personnel

Personnel have a duty to use PPE as instructed and store it appropriately when not in use. Defects or Loss shall be reported and the PPE promptly maintained or replaced. 3.7

Records

Records of PPE maintenance, risk assessments and training shall be kept by the employer. Issue of PPE shall be recorded if required by local regulations. 3.8

Identification of areas where PPE is required

Working areas on site where specific PPE is required shall be clearly identified (e.g. “Hearing Protection Required in This Area” signs). 4

PPE assessments and specifications

When performing a risk assessment, review work areas and tasks for general hazards (e.g., impact, penetration, compression, chemical, heat (or cold), harmful dust, and light (optical) radiation). Also consider specific sources of hazards such as: • • • • • • • • • • • •

sources of motion; e.g., vehicle movements (fork lift trucks, delivery vehicles), machinery or processes where any movement of tools, machine elements, or particles could exist, or movement of personnel that could result in collision with stationary objects; sources of high and low temperatures that could result in burns, eye injury or ignition of protective equipment, etc.; types of chemical exposures; sources of harmful dust; sources of light radiation, e.g., welding, brazing, cutting, furnaces, heat treating, high intensity lights, etc.; sources of falling objects or potential for dropping objects; sources of sharp objects which might pierce the feet or cut the hands; sources of rolling or pinching objects which could crush the feet; layout of workplace including working at height location of co-workers; ambient weather conditions; and any electrical hazards.

In addition, injury and accident data, work place inspections and audit findings should be reviewed to help identify other sources of hazard. The following sections contain general recommendations for the protection requirements for common tasks and the type of PPE to be used. They should be used as a starting point for the selection of the PPE required for any given hazardous situation and an aid to the minimisation of risk. Final selections should be based on a specific review of the work task, the duration of the task, the risk of injury during the task, the consequences of any exposure to an injurious chemical, any related chemical’s Material Safety Data Sheet, and any relevant regulatory or national consensus standard exposure limits. 4.1

Hearing protection

All hearing protection shall conform to the requirements of relevant, recognised standards. (2)

2

AIGA 066/10 The wearing of hearing protection shall be mandatory in areas where noise exceeds the regulatory levels. A sound level survey should be conducted to determine actual noise levels in areas where noise levels are suspected to be above regulatory levels (e.g., compressor buildings and platforms, pump rooms, process areas, turbines, high pressure gas vents, etc.). The choice of the hearing protection should be determined by taking into consideration both separately and in combination: – – – – – – 4.2

frequency of use noise level duration of exposure ambient noise level noise frequency additional PPE required for work activity (e.g. gloves, helmet, goggles etc). Eye and face protection

All eye and face protection shall conform to the requirements of relevant, recognised standard. (3) Eye and face protection for all tasks and work areas should be determined based on all hazards identified by the risk assessment. Standard prescription glasses shall never be considered as eye protection. Eye and face protection recommendations for various hazard categories are represented in the following table: Table 1—Eye and face protection selection Hazard Classification

Hazard

Consequences

• High voltage electricity • Medium voltage electricity • Arc flash

• Face burns • Eye burns • Blindness

Recommended Protection 1) • Safety glasses with side shields 4) • Arc-rated face shield 3)

1) The recommended protection devices are described generically and should be further classified to fit the appropriate

hazard. For example, goggles and safety glasses can be made out of different materials to protect against specific hazards. Safety glasses constructed from polycarbonate materials are a good compromise between weight and performance (resistance to scratches, hot particles, chemicals and UV) 2) Face shields should not be worn when working with gases or chemicals that create hazardous vapours. 3) A face shield with a hood might be required based on risk assessment. 4) Best practice in the US is to use safety glasses for all activities, including all low-voltage electrical work. See NFPA 70E (National Electric Code) for more information.

Face shields should not be considered primary eye protection and should be worn with additional eye protection (safety glasses or goggles) 4.3

Respiratory protection

All respiratory protection shall conform to the requirements of relevant, recognised standards. (4) Before entering a risk area (e.g., a confined space), the type and concentration of respirable contaminant should have been established by the risk assessment and confined space permit, so the appropriate respirator can be selected. Where the concentration of a contaminant is unknown, the use of supplied breathing air respirators is required. Specific respiratory protection shall be worn when personnel have the potential to be exposed to hazards above the regulatory limits. Minimum protection recommendations for various respiratory hazards are represented in Table 2. Table 2⎯Respiratory protection selection Exposure/activity Abrasive blasting Asbestos Chlorinated solvents use Confined space entry (where safe levels of oxygen or contaminant cannot be guaranteed) Inert cryogenic liquid fog or carbon dioxide release Dust Perlite
